アルペンスキー選手がパフォーマンスの向上と選手生命の長期化を実現するためには,スポーツ傷害のリスクマネジメントが不可欠である.そこで本研究では,日本選手をとりまくスポーツ傷害のリスク要因の特定と構造化を行った.日本選手24名(男性15名,女性9名)を対象とする半構造化面接を通して,リスク要因に該当する853のエピソードを収集した.Spörriら(2012)の先行研究を参照の上,専門家がエピソードの構造化を行った結果,39種類のリスク要因を抽出し,選手,道具,コース,雪質,気象,情報の6カテゴリに分類した.多重コレスポンデンス分析は,異なる組み合わせの4カテゴリを支持した.本記述研究の知見は,スポーツ傷害の潜在リスクを推定し,防止策を検討する上で有用といえる.

Yips is a long-term movement disorder consisting of fitful involuntary movements that occur in elaborate-skill-demanded motor behavior. Japanese baseball players have physical symptoms (i.e., sense of wrist being locked) and psychological symptoms (i.e., negative thinking) due to the onset of yips. Although, clinical psychological approaches with the goal of declining yips symptoms, improvement methods that can be easily carried out by on-site coaches and teammates have not been clarified. In order to establish easy-carrying improvement methods, the actual condition of yips player's surroundings should be clarified, but in fact, how yips players are supported by coaches and teammates also not yet been clarified. Thus, the purpose of this study was clarifying the actual supports that yips baseball player received from their teammates using qualitive study method. Result showed that teammates of yips baseball players do "Technical guidance," "Acceptance for yips symptoms," "Introduction of professional," "Proposal of practice menu," "Support for acceptance of yips symptoms." These supports correspond the concepts of social support.

The purpose of this research was to develop a swimmer-specific mental toughness inventory. In the pilot survey, semi-structured interviews were conducted with 7 Japanese individual sports Olympic medalists (4 males, 3 females) in order to identify the characteristics of elite swimmers’ mental toughness using a qualitative analysis method, the KJ method, considering higher- and lower-order structures. In the main research, a questionnaire regarding mental toughness was conducted on 254 swimmers (151 males, 103 females) who met the finishing time set by the Japan Swimming Federation with the purpose of enhancing swimmers’ competitiveness (assumed as elite swimmers in this study). The development of a swimmer-specific mental toughness inventory was attempted using a questionnaire developed by extracting swimmers’ mental toughness characteristics revealed in the pilot survey. After excluding defective answers, 194 (117 males, 77 females) samples were included in analysis. Exploratory factor analysis indicated that the inventory consisted of five factors and three items. After scrutiny of what constituted the extracted five factors, they were named the following: “Fortitude,” “Commitment to the Sport,” “Psychological Conditioning,” “Self-control,” and “Resilience.” Exploratory factor analysis was once again conducted through the maximum-likelihood method and Promax rotation and it confirmed internal validity. Conversion validity and divergent validity were examined, both of which adequately fulfilled the Goodness of Fit Index and standard path coefficient. Finally, adequate criterion-related validity was verified using correlation analysis with DIPCA.3. The factors of mental toughness in elite swimmers were similar to those in other sports. Japanese elite swimmers’ mental toughness characteristics were identified and a swimmer-specific mental toughness inventory was developed. This scale will be useful for helping coaches to understand Japanese elite swimmers’ mental toughness.

The purpose of this study was to clarify the subjective feelings of athletes wearing sunglasses while playing sports, using mixed methods research. In Study I, we conducted a free-answered survey, using 50 athletes (Mage = 30.6, SD = 6.6) to clarify subjective feelings of athletes wearing sunglasses while playing sports. Judging from the words of the athletes, data regarding “Physical feelings” (lessening straining of eyes, lessening sensory temperature, fostering performance, improving judgment speed, lessening overstraining, improving visibility, lessening wind effect, preventing drying eyes, and preventing foreign matters entering eyes), and “psychological feelings” (fostering concentration, switching a mood, enhancing motivation, lessening stress, feeling calm, and having psychological distance from others) were extracted. Next, in Study 2, we formed questionnaire items to assess the degree of subjective feelings of wearing sunglasses while playing sports and obtained the responses from 450 athletes (Mage = 21.5, SD = 6.7). We compared the subjective feelings between sports events (track and field, golf, baseball, and tennis). Results showed that track and field athletes scored higher in psychological feelings than baseball and tennis players did. We concluded that there are physical and psychological feelings of athletes regarding wearing sunglasses during sports, and that feelings about wearing sunglasses differ according to the sports events the athletes engage in.

統合失調症患者は中強度の歩行運動で快感情やリラックス感が増加し、不安感が減少、クロモグラニンA値やコルチゾール値が減少した。また、患者は一般成人より運動前から不安感やα-アミラーゼ値、クロモグラニンA値が有意に高く、運動後のアミラーゼ値の増加やクロモグラニンA値の減少が著しかった。患者は一般成人より体力が低いため、中強度の運動が精神的ストレス軽減をもたらす一方で身体的ストレスとなる可能性が示唆された。そこで、多様な運動強度に対するストレス反応を比較した結果、微細運動のフェルデンクライス・メソッドATMが低強度や中強度の運動よりも患者の心理的・生理的ストレス値の軽減に有効であることが判明した。
